Fern Parker: 解决：win10 打开cmd，然后运行命令：notepad XXX.tex，打开之后，将文件另存为就可以看到tex文件的编码不是utf-8，只需要另存为utf-8就好。之后，latexdiff生成的tex文件可能不能直接打开，需要再把编码方式由utf-8还原为之前的编码方式

Fern Parker: 大佬，这确实不影响下面继续执行

Fern Parker: 大佬，我接着往下执行latexdiff origin.tex modify.tex >diff.tex比较时，出现下面这两个问题，结果文件是空的 utf8 "\xBD" does not map to Unicode at D:/Program Files (x86)/CTEX2.9.2/CTEX/MiKTeX/scripts/latexdiff/latexdiff line 1314, chunk 1. Malformed UTF-8 character (fatal) at D:/Program Files (x86)/CTEX2.9.2/CTEX/MiKTeX/scripts/latexdiff/latexdiff line 2380, line 85145.

Fern Parker: 有大佬遇到过下面这俩问题 utf8 "\xBD" does not map to Unicode at D:/Program Files (x86)/CTEX2.9.2/CTEX/MiKTeX/scripts/latexdiff/latexdiff line 1314, chunk 1. Malformed UTF-8 character (fatal) at D:/Program Files (x86)/CTEX2.9.2/CTEX/MiKTeX/scripts/latexdiff/latexdiff line 2380, line 85145.
